Asymmetric aircraft's are fascinating so build an ssto out of it! I intend to try this myself one day as it's interesting.    Noob level: Make it fly. Bob level: Create an orbit around Kerbin.  Jeb level: Land on the Mun. Val level: Land on the Mun then return to Kerbin.   Here is a real life assymetric airplane for reference Blohm & Voss BV 141.
